Nuclides in carbon 14 dating Live nude chat punjab
Electron capture has the same effect on the nucleus as does positron emission: The atomic number is decreased by one and the mass number does not change.
Like positron emission, electron capture occurs for “proton-rich” nuclei that lie below the band of stability.
Beta (β) decay is the emission of an electron from a nucleus.
Iodine-131 is an example of a nuclide that undergoes β decay: Beta decay, which can be thought of as the conversion of a neutron into a proton and a β particle, is observed in nuclides with a large n:p ratio.
Although the radioactive decay of a nucleus is too small to see with the naked eye, we can indirectly view radioactive decay in an environment called a cloud chamber.
